Abstract: The fluid logic controlled elastic diaphragm switch matrix is formed of multiple elastic diaphragms having conductive surface portions in alignment with apertures carried by interspersed rigid sheets with the central elastic diaphragm carrying opposed and insulated conducting surfaces which are grounded when the switch point is open to act as shields. The matrix coordinate input pulses are amplified at each matrix unit to verify proper operation of the switch actuating fluid amplifier.
